Stalagmitron

Water dripping sculpture

A stalactite/stalagmite forms from water droplets and the dissolved solids therein.

The idea here is to create a dripping system (with perhaps faster accreting chemicals than those naturally found in caves) that would, from a 3D design (e.g. a Venus of Milo, or a David, or an arbitrary shape), create the necessary set of water sprouts and dissolved solids to create the design over a period of time, ideally faster than geological, so that results could be observed.

Description of similar accretion method, without the focus on precise controlled design. [Loris, Apr 13 2018]

       You just need higher ambient temperatures, although the flowstone produced may not be as smooth and dense as the naturally produced item.

       Sugar crystals?

       So technically I was right, it 'Is' a Transformer...   

       One of the Dinobots, surely?

       Perhaps a very slow 3D printer, consisting of a nozzle that moves under computer control in the horizontal plane, and every now and again drips a drop of calcium-bearing water onto the baseplate beneath?

       [+] Maybe do this with ice. Forming an actual rock formation would be more impressive, but an ice sculpture might be possible in hours or days.

       And I thought this would be some device for escaping from German prisoner of war camps. But, 1 bun.

       The thing is that it would continue growing after it was "finished"   

       Could some flow modelling system be used so that it grew and then blocked its own delivery rills?

       How would the undercuts be formed of a complex structure like a human figure? A pyramid type mound of various coloured strata would be easy but I can't see how anything else could be generated simply by the stalagtite process, but the author I'm sure can explain.

       Well, perhaps we can implement fans as well to add erosion? I suppose template forms would be cheating. Well, I'm sure Trump will come up with something.

       // I'm sure Trump will come up with something //   

       The warmth of his cheery, radiant smile will certainly evaporate the water faster. Keep the Democrats away - cold and slime won't help your sculpture to grow.   

       //How would the undercuts be formed //   

       Det cord.

       //How would the undercuts be formed // Cycles of different media with the final wash away cycles. -98°C methanol support for ice? A drippy Venus of Milo might be interesting.
